Data from: Bioclimatic envelope models predict a decrease in tropical forest carbon stocks with climate change in Madagascar
1. Recent studies have underlined the importance of climatic variables in determining tree height and biomass in tropical forests. Nonetheless, the effects of climate on tropical forest carbon stocks remain uncertain. In particular, the application of process-based dynamic global vegetation models have led to contrasting conclusions regarding the potential impact of climate change on tropical forest carbon storage. 2. Using a correlative approach based on a bioclimatic envelope model and data from 1771 forest plots inventoried during the period 1996-2013 in Madagascar over a large climatic gradient, we show that temperature seasonality, annual precipitation and mean annual temperature are key variables in determining forest aboveground carbon density. 3. Taking into account the explicative climate variables, we obtained an accurate (R2 = 70% and RMSE = 40 Mg.ha-1) forest carbon map for Madagascar at 250 m resolution for the year 2010. This national map was more accurate than previously published global carbon maps (R 2 ≤ 26% and RMSE ≥ 63 Mg.ha −1 ). 4. Combining our model with the climatic projections for Madagascar from seven IPCC CMIP5 global climate models following the RCP 8.5, we forecast an average forest carbon stock loss of 17% (range: 7-24%) by the year 2080. For comparison, a spatially homogeneous deforestation of 0.5% per year on the same period would lead to a loss of 30% of the forest carbon stock. 5. Synthesis: Our study shows that climate change is likely to induce a decrease in tropical forest carbon stocks. This loss could be due to a decrease in the average tree size and to shifts in tree species distribution, with the selection of small-statured species. In Madagascar, climate-induced carbon emissions might be, at least, of the same order of magnitude as emissions associated to anthropogenic deforestation.
Climate change and alpine-adapted insects: modelling environmental envelopes of a grasshopper radiation
<p>Mountains create steep environmental gradients that are sensitive barometers of climate change. We modelled the environmental envelopes of twelve predominantly alpine, flightless grasshopper species in Aotearoa New Zealand, using current conditions and two future global climate change scenarios: representative concentration pathway (RCP) 2.6 (1.0 °C raise) and RCP8.5 (3.7 °C raise). Two thirds of our models suggested a reduced potential range across species by 2070, but surprisingly, for six species we predict an increase in potential suitable habitat under mild (+1.0°C) or severe global warming (+3.7°C). However, when we consider the limited dispersal ability of these grasshoppers, all twelve species studied are predicted to suffer extreme reductions in range, with a quarter likely to go extinct due to a 96-100% reduction in suitable habitat. Alpine species are particularly vulnerable to the impacts of climatic shifts, and species that have limited migratory ability will be particularly at risk of habitat loss, fragmentation and local extinction. Here we present the predicted outcomes for an endemic radiation of alpine taxa as an exemplar of the challenges that alpine species, both in New Zealand, and internationally, will face in light of anthropogenic climate change</p>
